. Fig. ifa metal bar with lalarge-end c. n a `pin `over which `it passes. e an inclined plane for-the pin n tovback over the piece C The construction and operation of themachine `is as follows, reference being lhad to Fig. l in lthe drawings: Upon a strong wooden ,platform A, A,`I place the whole machine. From the cross piece at the top of the uprightsB,-B, I suspenda tin hopper C between whichfand theconductor E, E, is a broadtaperingtrough D, to the under side of `this a stiff Ispring Zisattached, having oneend Alying upon the octangular piece 179 which is made `to revolve bya bandpassing over the drum T and connected with a Inotive power. Whenthe pin p revolves, a jolting motion iis communicated to the hopper trough,and thepins, (which are thrown into the hopper in any quantity,) andmade to slide gradually down and fall into the ravine au at the upper end of the conductor E, E. Through the whole length of this conductor is `a slit, represented in lthe drawing by a heavy black line. When fthe pins fall into the ravine a er they roll to the center, the body passes throughand theyare suspended by the heads as seen in the section of 'the conductor, Fig, 2. The conductor is sufficiently inclined to cause the pins thus suspended to slide downthe slitand fall into lthegrooves gg, in the slide K. The conductor being stationary, the grooves arelled by passing the slide` K along under the lower end of the conductor, by `means of the rod with ahandle, P., As more pins might fall into the ravine of the conductor, lthan 'suffi cient to ll the slit, a portion ofthe conductor is beveled downwardfroin the center, 'as -seen `at `b b and` thes'unplu's pins ,slide over leo into the gutters F, F, from thence fall upon the inclined plane H, and then into a reservoir from whence they are taken and thrown groove is cut in its lower side, large enough to allow the heads of the pinsv that are in the slit, to pass through.v 1When the pins pass the curve of the conductor at C, they would be liable to fallout, or fall with the Y heads at irregular distances from the ends of the grooves. To prevent this, a flat upright plate shown by dotted lines and marked f, (or more clearly shown by the dotted lines d, rZ, Fig. 2,) is placed sufficiently near the conductor to have the heads of the pins strike it, and cause them to fall correctly into the grooves as they pass under the lower end of the conductor. The slide K with the grooves, having been passed along under the lower end of the conductor and the grooves filled, it is drawn back and arrested-in a proper position by the pin a.

A thin piece of metal 7- r keeps the pins in the grooves from being thrown out by the jarring of the machine in working. This piece is rounded on its lower edge, so that the plate I is allowed to easily pass under it.

This process completed, the pins are now ready to bestuck into the paper, which is performed thus. Upon the slide W is a metal plate V, the end at m being as broad as the slide. The other end is bent upward, so

. that, (as the plate works easily upon the screws) when pressed down by the thumb, the end at rises. The sheet of paper to be filled with pins is placed under this broad end, the thumb taken off of the point V and the springs Z1, h pressing upon the broad end, hold the paper securely to the slide W. The paper is then passed under the crimper M and the end thrown over back as indicated by the dotted line fu, u u; or the dotted line P, Fig. 3. The paper being thus made ready and the grooves filled with pins, the lever L is moved by the handle in the direction of the arrow. By this movement, the plate T is carried toward the pins in the grooves, and the crimper is made to perform its oflice as follows; When the plate I is moved forward by the lever L, the bar a a a, Fig. 3, which is attached to it, also moves, and its thick end c sliding under the plate J, J, passes over the pin n, which, being attached to the piece Z causes it to be drawn down a distance equal to the curve of the piece C. To eachend of Z (as best seen in Fig. 5) is attached two perpendicular rods ,m m (which are also seen at m, Fig. l). The upper ends of these rods are fastened by a nut to the springs N, N, and' near ,to the crimper M. As the' piece C passes over the pin n Fig. 3, Z

by means of its rods m m draws down the crimping bars Z, t, into the longitudinal grooves in the slide K, and thus the operation of crimping the paper is performed. Grooves or holes or notches are made through the crimping bars t Z, in positions to correspond with the grooves in the slide K, and large enough to allow the pins to pass easily through them when closed into the longitudinal grooves. The paper, by the 1 action of the bars and grooves, is raised into two folds, at proper distances upon the sheets, and when the pins pass through the notches vof the crimping bars, they penetrate these folds. At the moment the crimper completes the operation of crimping, the plate I, moved by the lever L, strikes the heads of the pins in the grooves, and forces them through the fold in the paper. At the same time the piece C Fig. 3, passes over the pin n which falls behind the perpendicular part, and allows the springs N, N, to throwv the crimper up. When the bar a, a a with the plate I is drawn back by reversing the motion of the lever L, the pin n passes up the inclined plane e, Fig. t and the piece C assumes its previous position as seen in Fig. 3. Thus the operation of crimping and sticking is performed, by a single motion of the lever L.

The movement of the slide WV, to which the sheet of paper is attached, is performed as follows: Attached to the slide W, is a straight rack e with the teeth some distance apart. Upon this rack, 'the rod O, 0,*operates thus. lVhen the lever L is moved in the direction of the arrow, the rod O, O, is drawn forward, and the moment the plate I has performed the oiiice of driving the pins into the paper, the attened end y of the rod O, O, falls in front of one of the teeth ofthe ratchet e. When the pins are stuck and the lever L is drawn back, the rod O, O, operating upon the ratchet, moves the slide V, back a given distance. This operation is repeated unt-il the rod O, O, traverses the whole length of the ratchet,

when, by a beveled piece of metal, the rod is R, which is made to press against it by theA action of the spiral spring lm. attached to the other end of the lever. This lever moves upon a hinge rivet in the center. The end of the lever to which the spring is fastened, is so formed as to fall behind the teeth of the ratchet, and prevent the slide WV, from being thrown back beyond va given distance each of Derby, Connecticut, for which Letters Patent were granted bearing date of Feb. 24, 1843. Also the series of grooves into which the pins fall, and the manner in which they are `laid into the grooves at the lower i end of the conductor, I do not claim as my invention, it being the same in form and operation, as a machine invented by Samuel Slocum of Poughkeepsie, New Yorkfor which Letters Patent were granted bearing p date of September 30, 1841.

\ I/Vhat I claim as my invention and desire to secure by Letters Patent isl. The combination of a sliding bed in which the grooves are cut for the reception of pins, with the stationary curved conductor, combined and arranged substantially in the manner and for the purpose herein set forth.

2. I claim thestationary conductors E, E, having two inclined bars with a downward curvature at the ends as described, and in combination therewith the gutters F, F, on each side into which the surplus pins pass, and are carried oE-the triangular piece (e) aiding in the operation. In the above claim I wish it to be understood that I do not claim the inclined conductors when 35 made straight but only with the curved terminations.
